The utility model relates to a testing device, which belongs to the field of mildew-proof performance testing of textiles, comprises a box body and a top cover, and is characterized in that micropore breathable filter membranes with the diameter of 100mm are arranged at central circular holes in the front, rear, left and right surfaces of the box body; two rows of slideways are arranged on the inner side of the top cover, and three stainless steel clips are hung on each row of slideways at intervals; and the top cover is tightly connected with the box body through a stainless steel lock catch. According to the utility model, a mildew-proof test sample can be hung on the stainless steel clamp of the top cover, and after spore liquid is uniformly sprayed, the top cover is fixed on the box body by the stainless steel lock catch. The microporous breathable filter membranes on the front, rear, left and right surfaces of the box body can prevent spores from diffusing out of the box to pollute the environment, and can effectively ventilate and moisture permeable, so that the temperature and humidity in the device are consistent with those of the culture environment. The suspension device is beneficial to effective implementation of a suspension method for testing the mildew-proof performance of the textile.

Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of textile mildew resistance performance test, and relates to a test device. BACKGROUND

[0002] The textile mildew resistance performance refers to the ability of the product to inhibit the germination of mold spores and the growth and reproduction of mycelium on the textile. With the increasing requirements of consumers on the quality and health safety of textiles, the demand for textiles with mildew resistance function in the market is also increasing. At present, the main basis for testing the textile mildew resistance performance is the standard GB / T 24346-2009 'Evaluation of textile mildew resistance performance', which stipulates two test methods, namely, clause 9.1 culture dish method and clause 9.2 hanging method. Since there is no currently available mildew test box on the market, the application of clause 9.2 hanging method is limited. SUMMARY

[0003] In view of the above problems, the utility model provides a test device for textile mildew resistance performance test, which solves the problem of limited application of clause 9.2 hanging method in 'GB / T 24346-2009 Evaluation of textile mildew resistance performance', and provides help for the effective implementation of the hanging method for textile mildew resistance performance test.

[0004] The technical solution of the utility model to solve the technical problem is as follows:

[0005] A test device, which mainly consists of two parts of a box body 1 and a top cover 2.

[0006] Further provided is that:

[0007] The box body 1 is a cube with a side length of 200 mm, and there is a circular hole with a diameter of 100 mm at the center of each of the front, rear, left and right four surfaces of the box body 1, and the material of the box body 1 is transparent glass material.

[0008] The central circular hole of each of the front, rear, left and right four surfaces of the box body 1 is a microporous breathable filter membrane 3 with a diameter of 100 mm, the pore size of the microporous breathable filter membrane 3 is 0.2 μm, and the material of the microporous breathable filter membrane 3 is acetate fiber.

[0009] The top cover 2 is a square with a side length of 200 mm, and the material of the top cover 2 is transparent glass material, which is connected with the box body 1 through a stainless steel lock buckle 4.

[0010] Two rows of slides 5 are arranged on the inner side of the top cover 2, and the distance between the slides is 60 mm. Three stainless steel clamps 6 are hung at intervals in each row of slides. DRAWINGS

[0011] Figure 1 It is a structural schematic view of the box body 1 of the utility model.Figure 2 The utility model discloses a top cover 2 structure schematic view.

[0012] 1 - box body;2 - top cover;3 - microporous breathable filter membrane;4 - stainless steel lock catch;5 - slide;6 - stainless steel clamp. Specific embodiments

[0013] As Figure 1 And Figure 2 Shown, a test device is by box body 1 and top cover 2 two parts constitute.The box body 1's front, rear, left, right four faces center position has the round hole of diameter 100mm, pastes and has the microporous breathable filter membrane 3 of diameter 100mm.The top cover 2 is connected with box body 1 through stainless steel lock catch 4.The inside of top cover 2 is equipped with 2 rows of slide 5, and every row of slide is suspended 3 stainless steel clamps 6.

[0014] When using, respectively the microporous breathable filter membrane 3 is pasted in the center round hole at every face of box body 1. Pick up top cover 2, and fix the sample on stainless steel clamp 6, and every stainless steel clamp 6 fixes one sample. Through the movement of stainless steel clamp 6, keep the proper distance between sample, to be not interfered with each other as the criterion. Again even spray the spore liquid of specified amount of mould on the surface of fixed sample, immediately cover top cover 2, and fix stainless steel lock catch 4, make it with box body 1 closely connected. Then place test device in constant temperature and humidity chamber, cultivate 28 days under 28 DEG C, relative humidity 85% condition. Because test device is mainly transparent glass material, the growth of mould on the sample surface during cultivation can be observed without opening the box, and it is safe and convenient.
